Variety has a brief report on television success for literary adaptions turning into publishing success. The obvious example is Charlaine Harris’s Sookie Stackhouse series which, boosted by the massive smash hit True Blood, have increased her sales across all her books. The article doesn’t mention the fact that all her Sookie novels were holding on to places on the New York Times Bestseller List (paperbacks) for weeks on end as the series surged in popularity week over week. We’ve had it at secondhand that sales of Harris’s books increased twenty-fold thanks to True Blood:

True Blood isn’t the only example, however. The Dexter series on Showtime has given the original novels (especially the first, which most closely formed the basis for the series) a significant boost, with sales having “have doubled every year since the series debut”. Another genre show, The Vampire Diaries, has helped sell a million additional copies of the series on which it’s based.

Random House is indicated as certainly being hopeful that HBO’s series will prove a success and will help fuel the growing fanbase for A Song of Ice and Fire. However, they do acknowledge that the significant length of the novels of the series—especially compared to the much shorter, lighter, self-contained Harris novels—mean that a greater commitment is needed from readers, and that this commitment may reduce the size of the boost in a series which is already very popular by any standard.
